The reliablemanner, thus effecting an immense upper end of the shaft is threaded.and adapt- 95 45 saving of time and labor. ed to a hand-nut, k, ontightening which the The framework A of the machine may be shaft will belocked and the worm-wheel renof any suitable construct-ion forsupporting the dered immovable, so as to become a nut for mechanismdescribed hereinafter. the screw G when the latter has to traverse B isthe reed, the lower bar of which rests the slide, the loosening of thenut setting the rco 5o in supports or sockets 50 on a bar, 51, whichshaft at liberty when it has to be used as a is secured to the frame ofthe machine, the means of traversing the slide by hand,in which case theworm acts as a pinion and the feedscrew as a rack.

L is the driving-shaft, which has its bearings in the opposite sides ofthe frame-work and extends under the center of the slide F from side toside of the machine. Oa one end of this shaft, and loose thereon, is thedriving-pulley M, Figs. 1, 5, and 7, also a balance-wheel, N, made in011e piece with 0r otherwise connected to the pulley, the motion ot' thebalancewheel being communicated to the d riving-shaft through the mediumof a friction-wheel, q, against which bears the face of the balancewheelN, and thisfriction-wheel, by means of feather-and-groove connections,can slide on but must turn with a short shaft, o', carrying at. itsinner end a bevel-wheel, s, which gears into asimilar wheel, t, on thedriving-shaft, Fig. 5.

'lhe friction-wheel qean be moved to and fr0 on the shatt by ahand-lever, a', to diminish or increase the speed of the machine, asrequired. 'lhe shalt r is provided with a crank; handle, 52, so that themachine maybe operated by hand when required.

The lever P, by which the balance-heel N is brought into Contact withthe friction-wheel q, is connected to a rod, b, the latter beingconnected by an intermediate lever to a sliding rod, c', having ahandle, d', by means of which the rod e may be moved in one direction toapply the balancewheel to the friction-wheel,

a spring, f', tending to force the rod in a contrary direction.

It will be seen, on referring` to Figs. 7, 23, and 27, that acatch-lever, 40, is pivoted to an arm, 4l,jointed to a bracket on theframework, and that a projection, e", on this catchlever enters a notchin the rod b', where it is retained by the action of a spring, 42. Theobject of this. mechanism will be explained hereinafter.

On that end ofthe driving-shaft opposite to that which carries thebalance-wheel, and outside the frame, is a eog-wheel,g, also abevelwheel, h', formed in the same piece with or otherwise connected tothe said wheel g' and both loose on the shaft, a spring on the lattertending to maintain a clutch, i', turning with the shaft in gear withthe wheels, and the clutch being operated through the medium of v an armon a rod, k', by a hand-lever, L', Fig. 2.

The wheel g' gears into an intermediate wheel, m', which in turn drivesa larger cog-wheel, n', revolving ou a stud projecting from theframework, Fg. 3.

To the outer face ofthe wheel a is secured a disk or plate, p', Fig. 18,to which is attached a toothed segment, q', the latter at eachrevolution v0f the wheel a engagingv into a small wheel, o', on the endof the feed-screw G, to which, when the machine is in operation, half arevolution is thus imparted, a single movement ofthe feed-screw takingplace at the completion of each second revolution of the driving-shaftL, this being necessary in a machine adapted for operation on twoheddles. If the machine is constructed for operating on three heddles,the gearing must be such that the feed of the carriage would take placeat every third revolution ot' the driving-shaft, and so on.

Against the periphery of the disk p' hears a disk, s', secured to thefeed-screw Gr, the disk s having two curved notches, 53, which tit theperiphery ofthe disk p', Figs. 3 and 18, and in this manner thefeed-screw is locked in 4position at'ter each movement and preventedfrom being accidentally turned before the proper time, which wouldproduce derangement of the partsand imperfect work or breakage. Vhcn thesegment q is broughtaround to engage the wheel o a curved notch, t', inthe disk p at the side of the segment allows the disk s to revolve,after which it is again locked, as before, by the disk p entering thenext notch 53. The warp-threadsfware successively drawn through theeyes, Fig. 25j), of the heddles, and between the dents ofthe reed B bymeans of a long needle,Q, Figs. 4, 5, and 6, provided at its outer endwith a hook, b2. This needle is placed within a tubular casing, lt,supported in a frame secured to the slide F, and is attached to acarrier, e2, which slides on the pai1A allelrods d'l and extends upthrough a longitudinal slot, 46, in the under side ofthe easing R, theneedle being attached to the carrier in such a manner as to admit ot'its being turned upon its axis, for a purpose described hereinafter.

To the needle-carrier c2 is pivoted a rod, e2, Fig. 5, whichis jointedto a link,f2, mounted on a stud, g2, and to the rod e is pivoted anotherrod, 11,2, which is pivoted to a lever i2, the latter having a pinpassing through a slot in an arm, k2, and this arm is secured to thestrap ot' an eccentric, Z2, at the upper end of a vertical shaftnz,having its bearings in the slide. This shaft has at its lower end abevel-wheel, a2, which gears into a bevel-wheel, p2, Fig. 7, arranged bymeans otl a feather and groove to slide upon but to turn with thedriving-shaft L, as the slide is traversed, the wheelp2 being held inplace, so as to be always in gear with the wheel a2, bya forked hanger,r2, extending down from the under side of the slide and titting within agroove in the hub qzofthe-whecl p2, Fig. 7 and thus, as the eccentric isrotated by the driving-shaft L, the needle Q; is reciproeated throughthe, medium of the connections described, a single revolution of thedriving-shaft causing the needle to be moved once forward and once back,

To the needle Q is secured a pin, s2, Fig. (i, which projects up througha longitudinal slot, t2, in the tube R, the said slot, near-the end ofthe tube, being so inclined as to turn the needle Q, on its axis to theextent of a quarter ot' a revolution, in order to bring its hook on oneside just before the completion of its forward movement, thus enablingthe hook to catch the warpthread w', after which, as it commences torecede, the needle is turned back to IOO IOS

its original position to again bring `the hook ,on the upper side,thereby preventing it from catching' the eyes ofthe heddles and thedents of the reed as it is drawn through them.

It will be advisable to give here a general explanation of the actionofthe reciprocating and interniittently-traversing needle Q inconnection with other devices, so that the detailed description givenhereinafter may .be more easily understood.`

Fig. 3G is a perspective outline, drawn without any regard to detailedconstruction, and in this tigure F is the intermittently-fed slide and Qthe reciprocating needle above referred to. At the rear ot' the slidethereis an extension consisting in the present instance ofaV bar, W, anda post, U, to t-hetopot' which is attached acarrier, T, the latter.having a projection with a sharp bearing-edge, d3. Thev meaning weintend to convey by the tei-tn sharp edge" is an edge made as sharp aspossible without reducing it to a condition vto sever the threads. Inthe'saine carrier, T, is a recess containing an oscillated disk providedwith a hook, C'. Above 'the carrier T is a pair of nippers, A', whichseizes a number ofwarp-threads and drags them alongthe sharp edge otlthe projection d3 toward the disk, the hook ot' which seizes one of thewarp-threads and moves it within range ofthe needle, the latter drawingthe thread back through the heddles and through the reed. Thread afterthread is thus operated on as the slide is fed intermittently in thedirection of the arrow, the carrier T, its hooked-disk B, and thenippers A' traversing with the slide.

The sharp bearing-edge d3, which is a vital part ot' the machine, isformed in the present instance on a'plate or blade, d10, secured to thecarrier. There is a projection, c3, on the carrier T, the object et'which will be explained in the detailed description given hereinafter.

S, Figs l, 2, 3, 4, and 6, is the warp-beam, thejournalsot'whichrestinsuitablesupportssecured to the tloor or to the frame-work, thebeam being prevented from unwinding by a springpawl and ratchet wheel,or by any other suitable device. The warp-threads 'w' from this beampass up over a guide-rod, e2, extending` across the frame-work, andthence between a stationary bar, wz, anda removable bar, a3, the latterbeing contined in place by the inclined guides b3 ot the frame, so thatby pressingthe bar ai* down the warp will be clamped tightly andprevented from slipping.` Some of the Y warp-threads are always betweenthe projection c3 and bearing-edge d3, Figs. 12 and 13, and as thethreads are removed other warpthreads take their places against thesharp bearing-edge d3 ot' thecarrier T while the latter is traversedwith the slide and needle.

The advantage ofthe sharp bearing-edge is that the warp-threads bearingagainst it have not the liability to'ridevover each other which theywould have if they bore against a tiator rounded edge.

Vby rounding the said projection and bearing- The entrance to the spacebetweenthe pro- 'ection c'3 and bearin -edUe cl3 is made tlarinrr h Dedge, so that as the carrier T is traversed the warp threads will bedirected into the said space. The warp-threads are led over a horizontalrod, e3, and thence down betweena stationary rod or bar,f3, and aremovable clamping-bar, g3, held in place by inclined guides h3 on thet'rz'une-work, which cause the said bar g3, when it is pushedl down, tobe wedged against the rod f3. The inner side of the bar g3, whichpresses aga-inst the warp-threads, is covered with felt, cloth, orequivalent material, 35, to allow each thread to he independentlywithdrawn by the needle Q without disturbing anyoftheadjacentthreads.Thebearing-edge d2 ot' the carrier T is so situated in respect to theclamping devices which hold the warpthreads that the latter will bearagainst the said edge d3. ing-edge is traversed in a direction parallelwith but at a short distance in front ot' the row of Warp-threads.

We will now describe the manner in which 1 the *arp-threads w' aresuccessively selected' and carried one at a time against the needle Qinto a position to insure their being` caught by its hook b2, so as tobe drawn thereby through the eyes of the heddles and .between i thedents of the reed.

The projection c3 and the bearing-edge d3 are at such distance apart. asto hold the threads parallel or side by sidein a single row and preventtheiu from riding over each other, Fig. l2, the threads nearest theinner end ot' the bearing-edge being stretched against the upper andlower stops or rests, i 7t3,Fig. 6,bythe act-ion ot' a pair ot'spring-nippers, A', which are pivot-ed at Z3 to thecarrier T, and arevibrated and alternately opened and closed by ymechanism describedhereinafter, the jaws of these nippers openingon their descent, so as topass clear ot' the threads, and closing thereon on their ascent withsufficient friction to take up any slack and produce a tension or strainon the said threads, the upward movement of the jaws in the are otl acircle having its center at Z3, tending also to draw the threads againstthe stops 'i3 7c3, Fig. 2.

In the under side of the carrier Tis formed a circular recess, m3, Figs.l0 and 11, into which is fitted snugly, but so as to oscillate freely, aflanged disk, B', the latter being supported in place upon a stud, a3,by means of a nut, 193, and an intervening spring, g3, this disk beingoscillated on the said stud a3 as a center through the medium of a.connecting-rod, r3, one end of which is attached to a crank-pin, s3, onthe under side of the disk and the other end to a lever, t3, which isactuatedby mechanism described hereinafter. YVithin thisdisk B ispivoted a-curved hook, C', Figs. l2 and 14, the point of which projectsout through a slot in the side of the disk into such a position as tocatch the innermost warp-thread ot' In other words, the said bear- IOOIIS

IZO

the series between the projection c3 and bearing-ed ge d3, and thus, asthehook G'is vibrated willi the disk B', a single thread is selected andseparated from the series and carried up against the needle Q,immediately behind the hook b2 thereof, Fig. 14, the needle having been,just previous to the movement ot' the hook C', advanced into the properposition to receive the thread, and turned so thatits hook b2 will bepresented on the side against which thethread is stretched by the hookC'. Hence on the retraction ot' the needle Q it will carry back with ita warp-thread.

In the side of the recess m3 is an annular groove, 'tt-f3, into whichthe point of the hook C' projects, and in which it moves, this groovethus allowing the point of the hook to project cut to a sufficientdistance to enable it to catch the thread.

In the bottom of the disk B is acurvedslot, 58, into which the threadenters as the disk is oscillated, this'slot thus causing the thread tobe carried inward toward the centerof thedisk and against the needle Q,a-s required. Just before this, however, the thread is released by theopening of the nippers A', so as to avoid nndue strain on and preventthe breakage ot' the thread.

In the periphery of the disk B is a groove, a, opposite to the groove w3in the side of the recess m3, the end of the plate d1", which forms thebearing-edge d3, extending into this groove cAk above the hook C',thereby preventing the thread from getting into the space between thedisk B and wall ot' the recess m3, and also pre-v venting two threadsfrom being caught by the hook C' at the same time. The distance te whichthe point of the hook C' projects is regulated by a screw, L4, Fig. 2l,or other equivalent device, as is necessary for coarser or finerthreads, so that but a single thread may be seized at a time, the screwb4 having a conical point, which bears against the inclined edge ot'thehook C', Fie. 2l and the s )rinda3 ress-v a 1 l o p ing the hookagainst the screw. Just before the needle Q has arrived at the end ofits forward movementitis brought into contact with a guard-plate, c4,Fig. 14, secured to the under side of the carrier T, this guard servingto guide the needle into the exact position required to insureitsreceiving' and catching the warp-thread when delivered by the hook C',the needle being thus supported and held up to its place against anytendency to spring to one side into such a position that it will miss athread.

For convenience ot' construction the projection c3 is provided with ashoe, d4, and-this shoe is furnished at its inner end with two smallprojections, c4 f4, the tirst overlapping andthe second underlapping theoscillating disk B', and both'serving as guards to prevent the threadfrom getting in between the disk 'and the sides of the recess m3, inwhich it oscillates; The shoe d4 is made adjustable on the projection c3by set-screws, as shown, so that it can be moved nearer to or fartherfrom the bearing-edge d3, as the thickness ofthe warp- Vthreads maysuggest.

At the inner end of the shoe d4, Figs. l5 and 16, is a small centralnotch, g4, to allow for the passage of the hook C', so that the threadaboutto be seized by the hook may remain between the projection c3 andbearing-edge d3 up tothe time ot' seizure. To still further prevent theliability of the warp-threads becoming crossed or riding over eachotherwhile between the projection c3 and bearing-edge cl3, and tostraighten or flatten them out, we employ a bell-crank lever, h4, Figs.13 and 22, which is pivoted immediately beneath the bearing-edge d3, theupper flattened edge, 60, of theleverlt' extending outand titting upclose to and under the bearing-edge cl3. At each movement of the curvedhook C', and just before it catches the thread, the lever h4, Figs. l()and 13, acted on by a spring, 39, is `moved by a bent lever, i4, whichis actuated by a spring, 7a4, attached to the adjacentlever, t3. By thismovement of the lever h4 its edge 60 is drawn down from the bearing-edged3 in contact with the threads, the rubbing action ot' the edge 60against the tightly-stretched threads thus serving to flatten orstraighten them out if accidentally crossed,the}, ointof the hook C'catching the thread at a point between the bearing-edge d3 and the edgeG0 of the lcver h4. By this device the catching of the wrong thread orof two threads at once is etfectually prevented.

We will now describe the manner in which the motion ofthe driving-shaftL is communicated to the mechanism connected with the carrier T.

D' is an inclined shaft, Figs. 2, 3, and 4L, carrying at its upper end abevel-wheel, Zt, gearing into a similar wheel, t, Fig. 2, previouslyreferred to, on the driving-shaft, and at the lower end of the saidshaft D' is another beveld wheel, m4, gearing into a bevel-wheel, n, ona IOO IOS

horizontal shaft, E', a bevel-wheel, p, being arranged by means of afeather and groove to yslide on but turn with the said shaft, and havinga grooved hub which is embraced by a forked hanger connected with theplate 59 of the slide F, Fig. l. This wheel p4 gears intoanotherbevel-wheel, g4, at one end of a shaft, r", which extends towardthe rear ofthe machine, and hasits bearings in arms projecting from thebar W, Figs. 2 and et. At the opposite end of the shaft r* is a smallbevel-wheel, s, which gears into a similar wheel, t4, at the lower endot an inclined shaft, G', extending diagonally through the standardUrand having its bearings therein. To the upper end of the shaft G' issecured a bevel-wheel, a4, whichl gea-rs into a similar wheel, fact, onthe end of a hori- Zontal shaft, c5, having its bearings in supports onthe carrier T, and having at its opposite end a crank, b5, to which ispivoted a connecting-rod, c5, the lower end ofthe latter being attachedto a slide, d5, which moves on a vertical guide, e5, secured to theunder side of the carrier T, Figs. 2, 4, 9, and 10. To the side of thisslide d is `pivoted a bent rod, /5, Figs. 2 and 4, the Aupper end ofwhich is pivoted to the nippers A', the latter, through the connectionsdescribed, being vibrated at the proper time. The nippers are composedot' the bar g1", pivoted to the carrier T, and the jaw g5, pivoted tothe bar. This movablejaw g5 of the nippers is connected b y a universaljoint to the bell-crank lever h5, pivoted to the carrier T, and causedby a spring, L5, to bear against a cam, Z5, on the shaft a5, so thatwhen the cam rotates the said jaw g5 will be opened and closed, Figs. 9and 1l. To the crank b5 of the shaft c5 is also pivoted anotherconnecting-rod, m5, the opposite end of which is attached by a universaljoint, 47, to the lever t3,

4 which is thusoperated at the proper times to produce the desiredresults.

We will now proceed to describe the mechanism employed for stopping themachine when a warp-thread breaks, or when a thread is missed by eitherthe vibrating hook'U or the .needle Q.

H' is a horizontal rock-shaft, Figs. 2, 4, 6, 24, and 27, having itsbearings in the framework and carrying near one end a crank-arm, a5, towhich is pivoted a rod, p5, the opposite end ofwhich is provided with awedge, g5, Figs. 23 and 27, adapted to be introduced between the rod b'.previously referred to, and the lever 40, Fig.v7, for the purposeofdepressing the latter and withdrawing its projection e' from thenotch`in the said rod L', thereby allowing the spring f' to operate theshipperlever P and stop the machine. An arm, 14:5, hung to the frame,Figs. 4, 24, and 27, is vibrated continuously as the machine operates,bythe combined action of a earn, 06,011 the shaft E', and a spring, c6,and to this arm is jointed a rod, 1.5, passing through asleeve, S5,pivoted to the arm Non the shaft H. Between the sleeve S5 and a collaron the rod t5 intervencs a spiral spring, a5, so that the rod is atliberty to bc reeiprocated whenthe arm t5 is stationary.

l', Figs. 2 and 2T, is a bent arm provided with acollar or hub, c,adapted to slide on but move with the rock-shalt H', this collar and armI' being caused to move with the standard U, forming part of the slideF, by a forked plate, d, which tits within an annular t however, or notbe carried under the plate g' by the needle Q,the dog e will turn by itsown weight and release the arm l', when the crank T5 will be operatedthrough the medium of the rod i5, the spring a5 being asufficiently-rigid medium through which to rock the shaft and cause the.wedge g5 to operate the lever 40 audigy' We will now proceed io describethe heddles l and the manner in which their eyes are selected andseparated one by one in proper order and held in position for thepassage of the hooked needle Q.

Each of the heddles D E is constructed in the manner shown intheperspective view,Fig. 29, in which, however, the eyes and heddlecordsare arranged at a. much greater distance apart than in the actualheddle, in order that our description may be more readily understood.The cords below every-eye ofthe heddle pass around the lower bar, g; butthe two cords au of one eye, 62, Fig. 29, pass up and over one side ofthe upper bar, e, while the cords c, above the next eye, 6,3, passupward and over theopposite side of the said bar c, and this alternationofthe upper cords of the eye is continued throughout the entire heddle.This heddle is ofthe kind madeby machinery, and is in common use. To thelower bar, g, of each heddle is temporarily attached, by means ot' ICOdowel-pins k6 or otherwise, a bar, Z6, Figs. 25

and 28, to which are pivoted two links, m6, the latter being jointed toa bar, a6, part of which is shown in Fig. 30. This device is introducedlongitudinallybetween the cords of the heddles in the manner bestobserved in Fig. 30, and by moving the bar a6 endwise, and therebyraising the saine,it will be brought directly under the eyes ot theheddles, Figs. 2S and 30, and will cause the faces of each eye to bepresented toward the front of the machine.

Between the cords of each heddle, above the eyes, passes a rock-shaft,p6, in the manner shown in Fig. 2S and more clearly in Figs. 30

and 35, the said shaft being adapted. to beari ings on the frame-work,these bearings and devices for actuating the rock-shaft being described.hereinafter.

A separating-arm, g5, (shown in perspective in Figs. 20 and 30,) isarranged, by means of a feather and groove, to slide on but rock withthe shaft p, and to traverse intermittently in unison with the feed ofthe carriage and needle. vIt should be remarked here that there isasudden intermittent endwise movement of the heddles, effected in themanner described hereinafter. 7e will now explain that function of thisoscillating separating-arm which consists, by co-operating with theendwise movement of the heddles and the traversing of the said scp- IOSIIO

aratingarm in unison with the slide F, in sefleeting eye after eye ofthe heddle for presenl tation to the needle.

The vibration of each separating-arm is in- 5 termittent, as ithesitates, while in a central position, in moving in both directions. InFig. 35 the separating-arm q, appertaining to the heddle D, has reachedthe limit ofits movement in the direction ot' the arrow, and in movingto this position has passed away from the eye 62, fof which a12 are the.Lipper cords. At the same time the separating-arm q keeps back the eye63, and consequently all the other eyes, whether their upper cords passon one side or the other ofthe upper bar, for if the eye 63 be kept backnone of the other eyes can pass it, for it must 'be remembered that thebar as maintains the eyes of al1 the heddle-cords in line. Hence thekeeping of one eye back must result in keeping back the adjoining eyes.Just as the separat ing-arm QG was leaving the eye 62 there was a suddenshort reciprocating endwise movement of the heddle, winch shook the eye62 free from the other eyes, as there is sometimes a tendency of thecords of the eyes to adhere to each other. On the return moy ement oftheseparatling-arm in a direction contrary to that pointed out by thearrow, Fig. 35, it stops midway between the two limits of its movement,for a purpose explained hereinafter, and then completes its movement ina direction contrary to that pointed out by the arrow, in doing which itleaves the eye 63 holding all the othersr back, and another endwisemovement of the heddle frees the said eye 63 from the other eyes. Havingnow described the selecting and separating functions of theseparatingarms, we will proceed to describe other duties which theyperform in connection with other devices. 1n Fig. 3() the needle Q, isapproaching the heddle D in the direction of its arrow, and the armV Q6of the heddle is stationary, but about to move in the direction of itsarrow, and separates'the eye 62 of the heddle from the remaining eyes.Before the point ofV the needle@ reaches the eye 62 ofthe heddle,however, the separating-arm QG has pushed thesaid eye 62 against alinger, s, on an arm, t6, Fig. 31, referred to hereinafter, and the eyeG2 is thus held between the separating-arm and finger, within range ofthe needle Q5, which passes through the eye and thence close to theseparating-arin Q6 of the next heddle, E, without going through one ofthe eyes of the latter heddle, as the nearest eye to the needle of thisheddle has been moved outof the way of the needle by a finger, IF, in amanner explained hereinafter. After the hook of the needle has seized awarp-thread itrecedes and drags the thread through the eye 62 of theheddle D and through the reed. After the needle in receding has passedfrom the eye 62 of the heddle D, and dragged thewarp-thread through thesame, the finger bl, acting on the knot at the lower end of the eye 62,movesthe said eye from the position shownin Fig. 31 to e, A 255,03s

that shown in Fig. 32, the end ofthe finger s6 yielding in order topermit the eye to pass from one position to the other. Immediately afterreaching the position shown in Fig. 32 the tingers s6 and if move backto their original positions, Fig. 33, (it will be seen hereinafter thatthe iingers move together,) and the eye 62 is now held out of the rangeof thel needle by the finger s6. In the meantime the separating-arm q isin a position to keep that eye ofthe heddle next to the eye 62 out ot'the way of the needle, and the eye 62 of the heddle D and the adjacenteyes ot' the same heddle are so tar apart that on the next forwardmovement ofthe needle it will pass between these two eyes, but throughone of the eyes of the hed- `dle E, which eye has been prepared for thepassage throughit of the needle in the same manner and by devicessimilar to those de.

scribed above as acting on the eye 62 of the heddle D.

It will thus be seen that daring one stroke, or forward and rearwardmovement, ofthe needle it passes through the eye of one heddle, D, andbetween the eyes of the other heddle,

E, and drags awarp-th read through the course it has pursued, and thatduring the next stroke of the needle it passes through the reed, betweenthe eyes ofthe heddle D, through one of the eyes of theheddle E, anddrags another warp-thread through this course, so that a. warp-thread isdrawn through an eye of one heddle and through the reed, and the nextwarp-thread through an eye ofthe other heddle and through the reed; andthis alternation is continued until a warp-thread has been passedthrough every eye of both heddles.

As regards the detailed construction ofthe separating-arm p6, it will beobserved on reference to the perspective view, Fig. 20, that a finger,c7, is pivotcd to one side ot' the said separating-arm, the outer edgeof this iinger being curved and the lower end provided with a projectionwhich slides in a segmental recess, d?, at the lower edge of theseparating-arm, the movement vof the tinger on the arm being restrictedby the ends of the recess, so that it cannot pass beyond the corners e7ofthe said separating-arm. the. finger is practically at rest,beiugcontined between the cords ot' the heddles, and bears thereonnearly down to the bottom ofthe eyes when the separating-arm visvibrated to one.

As regards the finger s, it is bestto make it in the manner illustratedin Fig. Set-that is, to provide it with alight spring, a, projectingbeyoud the rigid portion ofthe finger and bearing against thefinger Z-sothat when an eye ofthe vheddle has to pass from the position shown inFig. 31 to the position shown in Fig. 32 the it will be observed thatthree posts, r, Fig. 6.

spring will readily yield. The finger sf", however, may be constructedin a difftrent manner, so as to yield as described.

In order that the several operations above described may be effectuallyperformed, it is essential that there should be the following movementsof the different parts referred to:

First. A reciprocating movement ofthe needle, and the intermittenttraversing of the same with the slide F. The mechanism for effectingthese movements has been already described.

Second. The intermittent traversing of the carrier T, and the devicesattached thereto, in unison with the feed ot'the slide. This, togetherwith mechanism for operating these'devices, has also been explained.

Third. The intermittentsliding movement ofthe separating-arms inV unisonwith the traverse of the slide and needle.'

Fourth. The oscillating movement ofthe iingers s6 and if.

Fifth. The oscillating movement imparted to the separating-arms.

Sixth. The intermittent endwise-reciprocating movement of the hcddles.

We will now proceed to describe the meehanism employed for effecting thethird, fourth, fifth, and sixth movements.

As regards the third movementthe intermittent sliding motion oftheseparating-armsare secured at their lower ends to the rod and hence areintermittently traversed with the slide F, and in the top of each ofthese posts is a groove, 65, as shown in Fig. 6, and also in Fig. 28, inwhich, however, but two posts and one heddle are shown. The lower edgeof the sept'lrating-arm Q6, appertaining to the iirst heddle, D, isalways in the groove of the first post or that of the middle post, or inthe grooves of both of these posts, and the separating-arm appertainingto the second heddle, E, is always in the groove of the middle postorthat of the last post, or in the grooves of both of these posts, andhenccthe separating-arms must traverse on their rockshafts in unisonwith the intermittent traverse of the carriage F and its needle Q.

As regards the fourth movement-the oscillation of the fingersit will beobserved on reference to Figs. 26, 2S, 3l, 32, and 33 that the linger sis atthe upper end of an arm, t6, and the 'finger D7 at the upper end ofan arm, a7, both arms being connected to a hub, u, on the shaft10Q-which has its bearings on the framework of the machine, the. hub,with its two arms, being arranged by means of a feather and groove toslide on but rock with the said f shaft. At the same time the hub andits arms there be three heddles, three shafts for three devices. Avertical shaft, i7, Figs. 3 and 7,

earriesat its upper end a bevel-wheel, ic7,which gears into a similarwheel, li', above referred to, on the driving-shaft L, and to this shafti7 is also secured a bevel-pinion, L7, gearing into a bevel-wheel, m7,on a horizontal shaft, a7, at the opposite end of which is a wheel, p7,gearing into a wheel, Q7, on a horizontal shaft, N, the shafts Maud rlbeing supported in suitable bearings on the side of the frame-work A. Atthe rear end of the shaft if' is a bevel-wheel, a7, which gears into asimilar whetl, t7, on a short shaft, wl, carrying at its opposite endtwo cams, a, against which bear two rods, b, Fig. 17, which aresupported near the cams by passing through holes in a stationary piece,c, the opposite ends of these rods being pivoted to arms d.8 secured tothe .rock-shafts w and the rods being maintained incontactwith the camsby means of spiral springs e, which serve to move the shafts zo in onedirection, the cams moving them in the opposite direction,

and in this manner the cams and springs pro-' duce at the exact timesrequired the proper oscilla-ting movements of the fingers ,v6 and if asthe hubs a6 are moved along on vthe shafts w, as` above described.

As regards the tifth movement-the oscillation of the separating-arms-theshaft t carries a bevel-wheehf, which gears into a similar Wheel on thelower end of a vertical shaft, g8, carrying at its upper 4end abevel-wheel, which gears into a wheel, 7i, on a horizontal shaft, is,supported in bearings on the uprights b ofthe frame-work.' This shaft i8carries two scroll-cams, its, the groove in each of which is providedwith two straight portions and two double inclines, i3, on oppositesides of the cam, Figs. 3 and 28. Into these grooves fit the lower endsof two arms,m8, extending down from the shot t shafts h'l, formingcontinuations ofthe shafts p6, and thus, as the cams k8 are rotated, thedesired rocking movements are alternately imparted to theseparating-arms QG, the double inclines i8V of one caurbeing opposite tothe centers ofthe spaces between those ofthe other cam, in order thatthe movementsof the two rock-shafts and their separating-arms mayalternate as required.

As regards the sixth movement-the endwise-reciprocating lmotion of theheddles-it will beseen that the faces of the cams it are provided withprojections or tappets a8, Figs. l and 2S., which, as the cams revolve,are brought into contact with the bentlower ends of two rods,p8, whichpass through guides g8, and are pivoted at their upper ends to studsprojecting from two verticalrods, rfi, which are thus lifted each time,one of the .proiections IOO IIO

TIS

' ofthe sliding rods d and k, and thus, as they rockers are oscillatedthrough the connections described, the rods d and 7c are moved in thedirection oftheir length to operate the heddles in one direction, thespiral springs a9 returning them to their original positions on thereverse movement ofthe rockers S8. rllhe. rods d and it' are flattenedon their sides where they slide in theframe-work, and the recesses orgrooves in which they slide are open at the top to admit ot' their readyremoval, the rods being confined in place at one end by a bar or button,b9, which may be turned to one side when the rods are to be taken out.Soon after the hooked needle Q has drawn a warpthread through4 one ofthe eyes of a heddle and through the reed a revolving finger or` arm,e9, Figs. 3, et, and 2S, strikes the thread and draws it out of the hookb'j ofthe needle, and casts it over to one side, out ofthe way, thuspreventing the needle from carrying the thread back again on itsreturn-stroke, as it might otherwise do. This revolving finger isattached to the end of a horizontal shaft, d,

, Figs. 5 and 2S, having its bearings in the slide into the wheelp4 onthe shaft E', and in this manner the finger e9 is caused to perform itswork of drawing the thread out of the needle at the proper time, whichis when the said point Ihas been drawn back out of the path of the nger,so that the latter' will clear itas it rotates. Each ofthe rock-shaftsp6 is made removable to enable it to be easily taken out of the machine,one end titting into a springsocke'uf, while the other end slides withina socket, ,97, at the end of a short rock-shaftJtT, Fig. 19, having itsbearing in the frame-work, and forming a longitudinal extension of theshaft p6, a small projection in the socket gT entering the groove in thescroll-cainp, whereby the two shafts are caused to move together, asbefore described.

The above-dercrihed machine is constructed to operate upon two heddlesonly; but a machine may be made for operating upon three or moreheddles, in which case a series of antomatic devices the saine as abovedescribed will be required for each heddle-.-that is to say, there mustbe for each additional heddle a separating-arm, Q6, fingers s and 117,and mechanism for operating the same; also, meehanism for imparting areciprocating endwise movement to each additional heddle. The gearing bywhich the driving-shaft is connected with the feed-screw will alsorequire to be changed, as the number of strokes ofthe needle Q, betweeneach movement of the feedscrew G and slide F, must correspond tothenumber of heddles suspended within and operated upon by the machine; andthe relative sizes of the wheels must be such that for two heddles tworevolutions of the driving-shaft will cause the segment q to engage withthe gear o on the end of the feed-screw, for three heddlcs threerevolutions of the d riving-shaft, and so on, the segment q having theexact number of teeth necessary to turn the feed-screw and advance theslide F the proper distance to insure the accurate operation oftheneedle Q.

In operating the machine it is necessary that the first two or threeeyes of the heddles at each end should have two warp-threads passedthrough them instead of one, in order to form the selvagein theusualmanner. rllhis iseected by operating the clutch 'i' by the hand-lever lat the required time, so that the bevel-wheel It will not be rotated bythe driving-shaft, thus throwing out of action the various devices foroperating upon the heddles and producing the -feed ot' the carriageuntil the needle Q has drawn two threads instead of one through the eye,when the mechanism is again brought into action to bring the next eyeinto position, after which it is again thrown out to cause the secondeye to receive t-wo threads, and so on until the selvage has been drawnon that side, when the entire mechanism is thrown into action andallowed to continuein action until the needle Q has nearly reached theopposite end of the heddles, when the operation of alternatelydisconnecting and connecting the mechanism contro1le .l by the clutch t"is repeated to cause the selvage to be drawn at that end of the heddlcs,as required.

Having explained the construction of the different parts composingthemachine and the operation otdifferent features, we will now ldescribein brief terms the operation of the principal operating parts inrelation to each other.

We will suppose that the needle Q has reached the limit of its rearwardmovement, that the screw G has fed the slideF to the desired extent, andthat the needle is about to commence its for 'ard movement. rlhewarpthread about to be seized by the needle is with others between thejaws of the nippers A (whi'ch,however,havenotyetseized the thread) andagainst the bearing-edge d3, the point of the hook U ofthe disk B is atits greatest distance from the thread, which it has to subsequentlyseize, the separating-arm {16,appertaining to the heddle D,is in the actot' pushing the eye 62 ofthe said heddle against the linger si", whichis stationary, and the separating-arm g, appertaining to the heddle E,is quiescentin its central position, where it keeps the eyes ofthe saidheddle E away from the course of the needle. 7e will now suppose thatthe needle is in the act of moving forward and has passed through thereed. Before its point reaches the eye 62 ofthe heddlel) the separatingarm of that heddle has completed its duty, and is stationary in itscentral position, whileit holds the eye 62 of the heddle against thefinger s6, so that it will bein a proper position to receive IOO IIO

IIS

the point ofthe needle. In the meantimethe u separatin g`arm and in gerss" and bhappertaining to the other heddle, E, are in the act ofp'er`forming theduty of separating the eye last threaded of that heddle fromthe other eyes, so as to clear the wayfor the needle and prevent it frompassing through any eye of the said heddle. The needle, having passedthrough the reed, through the eye 62 of the heddle D, and between thethreaded eye and next eye of the heddle E, is approaching the limit ofits forward movement. Beforeitreaches this point, however, the nippers Ahave seized a ntnnber ofthreads, including that destined to he caught bythe hook of the needle, and `have drawn the threads upward, as well aslaterally against the fingers Z2 and k3, so that the first thread of theseries will be pressed against the periphery of the oscillating disk Band in a positionto be seized by the hook C of the said disk. When theneedle has reached, or very nearly reached, the limit of its forwardmovement, Fig. 14, the disk B suddenly turns to such an extent that itspointed hook seizes the first warp-thread and drags it into the curvedslot 5S of the disk and against the needle, which had turned on its axisbefore reaching this point. The needle no sooner reaches the limit ofits forward movement than it commences to return, in doing which itshook catches the warp-thread, and the disk turns back so that its hookloses control of the thread, which is now drawn away, by the receding'needle, from between the rod f 3 and the felt of the bar g3, and awayfrom the other warp-threads, through the heddle E, without passingthrough one or" its eyes, through the eye 62 of the heddle D, andthrough the reed, after which its thread is removed from the needle bythe hook c. While the needle is in the act of thus receding an eye ofthe heddle E is being prepared by the devices and movements abovedescribedfor receiving the needle during its next forward movement, andthe eyes of the heddle D are being so arranged in the manner and by theappliances described that during the next forward movement of the needleit will pass between eyes and not through an eye of the said heddle.When the needle has arrived, or nearly arrived, at the limit of itsrearward movement, the carriage is fed to' the desired extent and arepetition of the above-described operations takes place.
